All,
I have some code that I have been working on that crashes R (1.8.1 on MacOS
X installed from source). Here are excerpts of the code and data
structures. When the lists that I am using to construct the data.frame are
truncated (shortened), R catches the differing rows and warns. However,
when the entire lists are used (I haven't looked for an exact breakpoint or
for a particular list value), segmentation fault occurs. I suppose that I
could send individuals the data if that would help.
Thanks,
Sean
